With my car having a type 1 inlet for charging, I need a type 1 to type 2 cable to charge on untethered EVSEs generally found for AC charging in public. These cables are usually pretty expensive, even used. I made one up for just over £30. The video below contains the details. Here I am grabbing some juice at a local carpark, I have a 3.3KW charger on board, so this is the maximum rate for my current setup. These particular EVSE's have a 3 phase connection and can in theory top out at 22KW.
